The source of the Columbia River is offically Columbia Lake in British Columbia, Canada, which lies at an elevation of 2690 ft (820 m). It empties into the Pacific Ocean where the elevation is 0 (since elevations are measured as height above sea level). The river is 1,243 miles (2,000 km) long so the gradient would be 2690/1243 = 2.164 ft/mile or 820/2000 = 0.41 m/km which comes out to 4.1x10-4 ft/ft or m/m.
